Abstract

Eljárás és berendezés szilárd részecskék szeparálására fluidágyasreaktor reakciókamrájából (20) kiáramló gáztól olyan centrifugálisszeparátor elrendezésben, amely tartalmaz egy horizontális iránybanvertikális irányú planáris vízcső panelekből álló falak általdefiniált örvénykamrát (70, 70', 70<), amely falak belseje legalábbrészben hőálló burkolattal ellátott, és amely falak az örvénykamrábanolyan gázteret definiálnak, amely gáztérben legalább egy vertikálisgázörvény (84, 84') létrejön, továbbá tartalmaz legalább egy, a gázszámára a reakciókamrából a gáztérbe történő bevezetésére alkalmasbemeneti csövet (82, 82'), legalább egy, a megtisztított gáz gáztérbőltörténő elvezetésére alkalmas kimeneti csövet, és legalább egy, aszeparált szilárd részecskéknek a gáztérből történő kivezetésérealkalmas visszavezető csövet. A találmány lényege, hogy aszeparátorösszeállítás biztosítja, hogy a reakciókamrából kiáramló gázaz örvénykamrában legalább egy, a külső falak belső oldalán hőállóburkolattal lekerekített, és a sarkot alkotó vertikális irányú külsőfalak által bezárt legalább 108 fokos szöggel rendelkező sarokkalütközzön. ÓMethod and device for separating solid particles from the gas flowing out of the reaction chamber (20) of a fluidized bed reactor in a centrifugal separator arrangement that includes a vortex chamber defined by walls (70, 70', 70<) consisting of horizontal and vertical planar water pipe panels, the inside of which walls are at least partially covered with a heat-resistant cover, and which walls in the vortex chamber define a gas space in which at least one vertical gas vortex (84, 84') is created, and also contains at least one inlet pipe (82, 82') suitable for introducing the gas from the reaction chamber into the gas space, at least one suitable for removing the purified gas from the gas space outlet pipe and at least one return pipe suitable for discharging separated solid particles from the gas space. The essence of the invention is that the separator assembly ensures that the gas flowing out of the reaction chamber collides with at least one corner in the vortex chamber, which is rounded on the inner side of the outer walls with a heat-resistant cover and enclosed by the vertical outer walls forming the corner, with an angle of at least 108 degrees.
